pledal 20, enabling the conductor to closet e doors when his hands are busily engagedwith other matters connected with his duties.

' jThe'several contact boxes 8 are adapted to contain the endsof wires between which exist the gaps forming normally'broken C11- cuits, said circuits being suitably arranged to efiect the door opening and closing move- .m'entsand the energization of a signal for the motorman. Of course, arrangements can-be made for any other circuits which it ma' be desired to operate from the conductor s osition on the platform, the ones disclose being sulficient to illustrate 'the broad idea. in this connection. In-Fig. 2, the push buttons 24, 25 and 26 are for controlling '27 is. a-wire28 which is'connected to a re-- these circuits.

Referring now to Fig. 6, the controlling circuits for the several mechanisms,'will be understood. Leading from the positive line sistalnce coil 29 connected up to a controller 30, said controller being connected by-a wire 31 with the solenoid 32 which is grounded at 33 in the negative line 34. The energization of the solenoid 32 serves to elevate the plunger 35: together with'a switch lever 36, to which said plunger is connected, said lever 36 being pivoted at 37 to adapt it to close a; circuit througha wire 38, switch 36, contact 39, wire 40, resistance 41, wire 42, armature 43 of the motor, field coil 44and wire 45 which is groiulded in the line 34.. 'A-

branch circuit issimultaneously energized .by the closure of switch 36, said branch cir-; cuit including wire146 which 'is connected to the wire 40 adjacent the coil 41, solenoid 47, wire 48, field winding 44 and wire 45 which is grounded in line 34.f The function of this circuit is to energizesolenoid 47 when the circuit is closed by switch 36 and current supplied to the motor 43-44, the solenoid 47 being designed to maintain an armature 49in elevated position with respect to a .pair of contacts 50 included in the door by the drop of switch 36 and whilethe car is still in motion, a lesser circuit is provided wherein the motor Thus ajlaterallyj extendingbranch 51 is connected 'to' the wire-.42'and' a similar branch-52 is ccnnected'tothe wire 48, said branches being provided withspaced contacts. 53. Normallysuspended above thecontacts 53 and adapted to brid e the space thercbetween; is an armature provided with a stemi'or plunger l55 subjcct to the solenoid. 56 wliiehis woundfupon the hollow core 57 'within -whi'chfitlie.plunger 55 reciprocates. The ener'grz tttidn of-the solenoid 56= is normally mainta nedby current debecomes a generator;

rived from wire 31 bymcans of a branch wire 58 when'the controller 30 is properly manipulated for this purpose. The solenoid 56 is connected to the win: 45 which is grounded in line 34.

provided with current through the switch 36, the solenoid 56 will also be supplied with the current necessary to maintain the armature 54 in raised position. On the other hand, as soon as the current is cut oil from the motor by dcncrgizing the solenoid 32,

the solenoid 56 also becomes ded'nergized and the. armature falling upon the contacts 53 closes the lesser circuit and servesto mainso tain the 'energization of the .solenoid. 47 by current derived from the motor as a generator. Suitable and efficient means are provided for moving the door 59, by attaching thereto a rod 60. On the end of said rod is a piston '61 adapted to reciprocate in the cylinder 62, said cylinder being connected by a pipe 63to a valve housing 64, said housing being connected to an air reservoir 65 by means of a, pipe 66. A second rod 67 is rigidly connected to the first rod-60, in the manner indicated-in Fig. 6, and is provided with a piston 68 which is ada ted to reciprocate in the'cylinder '69. aid

cylinder 69 3 s connected by pipe.70 with) the valve housing'64. Controlling the valve in the housing 64 is alever arm 71 which is connected atits outer end with a plunger rod 72 which is adapted be moved first in one direction andthen the other by means of solenoids. 73 and 74. Thesolenoids 73 and 74 are" grounded in-the'line 34 by the; wire 75 which is common to both of them; Awire 76 connects the solenoid 73 with the press button 24 while a wire 77, leads from the press button 25 to the" solenoid 74. A

the solenoid 74. A wire 82 which is oonnected to the pedal 20, joins the wire 78 at 83 so that when the armature 49.closes thegap between contacts 50, any oft-he-following-circuits may be closed. First, to' open the door 59,.push' button 24 is manipulated to close a circuit including wire 79,,contacts' 50, armature 49, wire 78, wire 76,s0lenoid- 73 and wire 75, the solenoid 73 being-energized to move the plunger 72 .to the .left, 12 thus admitting air or other through the pipe 70 into the cylinder 09. Second, by pressing button 25, acircuit is completed through wire 79', contacts 50, -a,rmatu re 49,
